Bisparse Blind Deconvolution through Hierarchical Sparse Recovery
Axel Flinth, Ingo Roth, Gerhard Wunder
The hierarchical sparsity framework, and in particular the HiHTP algorithm, has been successfully applied to many relevant communication engineering problems recently, particularly…
In Search of Projectively Equivariant Networks
Georg Bökman, Axel Flinth, Fredrik Kahl
Equivariance of linear neural network layers is well studied. In this work, we relax the equivariance condition to only be true in a projective sense. We propose a way to construct…
One-Shot Messaging at Any Load Through Random Sub-Channeling in OFDM
Gerhard Wunder, Axel Flinth, Benedikt Groß
Compressive Sensing has well boosted massive random access protocols over the last decade. In this paper we apply an orthogonal FFT basis as it is used in OFDM, but subdivide its i…
Rigidity Preserving Image Transformations and Equivariance in Perspective
Lucas Brynte, Georg Bökman, Axel Flinth +1
We characterize the class of image plane transformations which realize rigid camera motions and call these transformations `rigidity preserving'. In particular, 2D translations of…
